I have a 5d2 with ML installed and very much like the features it provides. I have only 1 qualm with it regarding powering up from a period of inactivity.
It takes almost 1.5-2 seconds to power up the camera from the time i hit the shutter button to wake up the camera. On the contrary, without ML the same process is almost instantaneous. ML has caused me to miss a few shots because of this long period of "waking up".
I tried looking thru the menu and ML manual and there's nothing on this. Any advice?
